Screen scrape an applet?

Thread view:

Can anyone give me a pointer or ideas on how I could capture the screen
output from an applet (such as a stock quote ticker) which refreshes
periodically?

Thanks, Dan

Why the screen output? Surely it would be better to get
at the textual information. ..The information supplier
being in full compliance with this, will probably provide
an API.

Maybe, the class java.awt.Robot will help you. Note that this is not
available in old Java versions which may cause problems when using in an
applet.

Note also that an applet would need to be signed to invoke
most of the Robot methods of interest.

Andrew and Ingo,

Thanks for your comments.

I'll look at both approaches.

If you're trying to scrape the information, rather than just bitmaps,
from a third party applet I'd suggest feeding it a custom Graphics2D
object. Probably straight through it's update method.
